Abstract (en)

In various embodiments described herein, a device comprising a light guiding layer (105) optically coupled to a photocell (100) is described. A plurality of surface features (108) are formed on one the surface of the light guiding layer. The surface features (108) can comprise facets that are angled with respect to each other. Light (112) incident on the surface of the light guide is redirected by the surface features and guided through the light guide by multiple total internal reflections. The guided light (112) is directed towards a photocell (100).
